The Northwest Coast is the coastal regions of the Pacific Northwest and the Northwest Plateau (also commonly known as "The Interior" in British Columbia and the Inland Empire in the United States) is the inland regions. The term "Pacific Northwest" should not be confused with the Northwest Territory (also known as the Great Northwest, a historical term in the United States) or the Northwest Territories of Canada.

Five aircraft were ordered for the round-the-world flight, one for testing and training and four for the actual expedition. The success of the World Cruiser bolstered the international reputation of the Douglas Aircraft Company. The design of the DWC was later modified to create the O-5 observation aircraft, which was operated by the Army Air Service.

Design and development

In 1923, the U.S. Army Air Service was interested in pursuing a mission to be the first to circumnavigate the earth by aircraft, a program called "World Flight".Donald Douglas proposed a modified Douglas Aircraft Company DT to meet the Army's needs. The two-place, open cockpit DT biplane torpedo bomber had previously been supplied to the Navy, thus shortening production time for the new series. The DTs to be modified were taken from the assembly lines at the company's manufacturing plants in Rock Island, Illinois and Dayton, Ohio. Douglas promised that the design could be completed within 45 days after receiving a contract. The Air Service agreed and lent Lieutenant Erik Nelson, a member of the War Department planning group, to assist Douglas. Nelson worked directly with Douglas at the Santa Monica, California factory, to formulate the new proposal.

National Geographic (magazine)

National Geographic, formerly The National Geographic Magazine, is the official magazine of the National Geographic Society. It has been published continuously since its first issue in 1888, nine months after the Society itself was founded. It primarily contains articles about geography, history, and world culture. The magazine is known for its thick square-bound glossy format with a yellow rectangular border and its extensive use of dramatic photographs.

The magazine is published monthly, and additional map supplements are also included with subscriptions. It is available in a traditional printed edition and through an interactive online edition. On occasion, special editions of the magazine are issued.

As of 2015, the magazine is circulated worldwide in nearly 40 local-language editions and had a global circulation of 6.8 million per month. Its U.S. circulation is around 3.5 million per month.

Seattle Fault

The Seattle Fault is a zone of multiple shallow east-west thrust faults that cross the Puget Sound Lowland and through Seattle (in the U.S. state of Washington) in the vicinity of Interstate Highway 90. The Seattle Fault was first recognized as a significant seismic hazard in 1992 when a set of reports showed that about 1,100 years ago it was the scene of a major earthquake of about magnitude 7, an event that entered Native American oral legend. Extensive research has since shown the Seattle Fault to be part of a regional system of faults.

Notable earthquake

First suspected from mapping of gravitational anomalies in 1965 and an uplifted marine terrace at Restoration Point (foreground in picture above), the Seattle Fault's existence and likely hazard were definitely established by a set of five reports published in Science in 1992. These reports looked at the timing of abrupt uplift and subsidence around Restoration Point and Alki Point (distant right side of picture),tsunami deposits on Puget Sound, turbidity in lake paleosediments, rock avalanches, and multiple landslides around Lake Washington, and determined that all these happened about 1100 years ago (between A.D. 900–930), and most likely due to an earthquake of magnitude 7 or greater on the Seattle Fault.

The 900 A.D. quake produced 21 feet of sudden uplift at some locations. The potential for that type of extreme ground shifting under our biggest city has scientists, engineers and emergency planners concerned.

Addresses the question, "How will 3 buildings, engineered equally, on different bedrock react to an earthquake? "
Highly generalized animation reflects the arrivals of P, S, and surface waves to 3 closely spaced buildings. Exaggerated movement of the buildings reflects the relative motion recorded by the seismograms. The 4th building on the beach shows the effect of liquefaction of underlying sediment. Animation ends with actual seismograms from buildings on solid bedrock and sediment fill equal distance from the 1989 Loma Prieta M7 earthquake.

Geology of Seattle and the Puget Sound

The hills and lakes of Seattle, Washington are a direct result of multiple Puget Lobe advances during the Ice Age. Beneath the drumlins, outwash, glacial troughs, and scattered glacial erratics lies the Seattle Fault, an active fault which has produced numerous magnitude 6 or higher earthquakes since the Ice Age.
Interstate 90 exposes much of this geology in its first few miles heading east from downtown. The freeway begins on old tidelands that were filled by early residents of Seattle. Hills composed of soft glacial deposits were moved and dumped into Elliot Bay to make new land for a growing city. Today’s SODO district - including stadiums for the Seattle Seahawks and Seattle Mariners - sits on filled tidelands that are especially prone to seismic shaking during the next big ear...

OPB's Oregon Field Guide presents "Unprepared".
This Documentary is part of an integrated radio, TV and online effort that examines our region's vulnerability to a mega-quake. The Pacific Northwest has seen earthquakes before. But Cascadia subduction zone earthquakes are completely different—and will trigger massive destruction from British Columbia to California and produce tsunamis that can wipe entire towns off the map. The geologic record reveals that they strike every 300 to 500 years. The last one was in 1700. Can we prepare? How? And what lessons can we learn from earthquakes elsewhere?
OPB has launched a new initiative to inform people of the dangers of the Cascadia Subduction Zone mega-­‐quakes. Oregon Field Guide sent a team to Japan to look at the effects of the 2011 earthqu...
